ENPHO is promoting sustainable sanitation systems that are financially viable, socially acceptable, technically and institutionally appropriate, and environmentally safe. ENPHO is providing services on wastewater management; faecal sludge management and developing sanitation systems for urban and peri-urban areas and emerging small towns in Nepal.

The rapid population growth and haphazard urbanization have resulted to the increment in waste, wastewater and faecal sludge. It has been imperative to address the issues of solid waste management, wastewater management and faecal sludge management. Through the implementation of various urban sanitation focused projects and programmes, ENPHO is supporting for capacity enhancement, formulation of policies and frameworks, public awareness and outreach campaigns on urban sanitation and providing the technical support for the development of treatment plants and systems. Additionally, ENPHO has also piloted Sanitation Safety Planning in Nepal to ensure safety from toilet to table. On top of that, ENPHO has piloted the application of ISO 24521 guidelines for the management of basic on-site domestic wastewater services and thereby help to improve environment sanitation conditions. Furthermore, ENPHO has technically supported Mahalaxmi Municipality to approve and publish Faecal Sludge Management (FSM) By-Laws which is the first-ever on-site sanitation legal instrument in Nepal – “Rajpatra” publication.
